ABSTRACT
This chapter describes analytical models and a finite element analysis methodology for evaluation of compaction-induced soil stresses and resulting soil-structure interaction effects. These analytical methods model the incremental placement and compaction of soil, and are based on a hysteretic model for residual soil stresses induced by multiple cycles of loading and unloading. Compaction loading is realistically considered as a transient, moving, surficial load of finite lateral extent, which passes one or more times over some specified portion of the fill surface at each stage of backfill compaction. These analytical tools are well-supported by field case history studies.
